--erase-all hit the exact same "ROM does not support function erase_flash"
error as a standalone erase_flash — confirmed live: esptool's --erase-all
is implemented as the same full-chip-erase command, not a per-sector loop,
so it needs the stub just as much. The real fix isn't finding another way
around the ROM bootloader's limitations — it's restoring the stub Debian's
package is missing.
Fetched the exact missing file (stub_flasher_32s3.json) from the matching
upstream esptool release tag and installed it directly on archy-x250-dev;
verified live with a read-only `flash_id` that stub mode now loads
("Uploading stub... Running stub..."). Removed --no-stub from flash.rs now
that normal stub-loader mode works correctly (faster and fully-featured vs.
the ROM-only fallback). scripts/self-update.sh now fetches and installs
this same file automatically whenever it's missing, so this isn't a
one-off manual fix tied to a single node.
